Continuity mistake: At the start when Grace is running across the campus to Jim, the items she's holding rearrange in her arms between shots (note the grey blanket which is over her left arm, then under her right.) (00:01:30)
Continuity mistake: When Grace is getting changed in the car, she pulls on a pair of jeans and then pulls her blue shirt off over her head. In the first shot she is pulling it over her left side of her head. In the next shot she is pulling it off over the right side. (00:02:20)
Continuity mistake: As Jim and Grace are driving down the road, a dragonfly splatters onto their windshield. Between shots the size and shape of the splatter changes, and continues to as Jim attempt to wash it off with a bottle of water. (00:03:35)
Continuity mistake: When Jim and Grace are driving away from the police in the stolen sheriff car, they are shot at and the back tailgate and left wing mirror are broken by gunshots. But in following shots you can see both parts of the car completely intact again, the broken, fixed, etc. (00:48:40)
Continuity mistake: When we see the dead bodies of Harlan and the policeman laying in the office as Lt. Esteridge is looking at them, you can clearly see the "dead bodies" breathing. (00:40:50)
